Description
Die Erfindung betrifft ein Ausgleichssystem für den Antrieb eines in Gleilführungen hin und herbewegbaren Walzgciüstes eii.js Kallpilgerwal/werkes, bei dem das Walzgerüst über eine senkrechte Kurbelwelle und wenigstens eine an einer Kurbeiwellenkröpfung angeschlossene Verbindungsstange angeirie'-^n isl und an der Kurbelwelle eine, um die Kumclwellenachso umlaufende Ausgleichsmasse befestigt ist. Die Erfindung geht damit von dem durch die DKAS 18 15 521 gegebenen Stand der Technik aus. Hierbei isl /war ein vollständiger Ausgleich der Masscnträghcilskräfte gegeben; nicht verwirklicht ist jedoch ein Drehmomentausgleich The invention relates to a compensation system for the Drive a reciprocable in slide guides Walzgciüstes eii.js Kallpilgerwal / werkes, where the roll stand via a vertical crankshaft and at least one connected to a crankshaft offset Connecting rod angeirie '- ^ n isl and an the crankshaft one to the Kumclwellenachso circumferential leveling compound is attached. The invention thus proceeds from that provided by DKAS 18 15 521 given state of the art. This was a complete compensation of the inertial forces given; however, a torque compensation is not realized
Dichinomenl- und Massenausglcichssystcme. die dii durch die zyklische Beschleunigung und Abbremsung des Wal/gerüstcs di.-s Kaltpilgerwal/werkes hervorgerufenen nachteiligen Drehmomente kompensieren, sind beispielsweise in den US-PS 29 24 106 und 33 35 593 bzw. DRAS 14 27 951 beschrieben. Erreicht wird der Drehmomentausgleich durch die Vorsehung von zusätzlichen Ausglcichsmassen. die an der Kurbelwelle befestig! sind. Gemäß vorgenannten Druckschriften sind die zusätzlichen Ausgleichsmasscn z. B. in einer tiefen Grube angeordnet, wo sie entweder auf- und abgleiten oder aber Pendelbewegungen ausführen. Vorrichtungsmäßig ist bei dieser Lösung eine Verbin dungssiangc von der Ausgleichsmasse zum Kurbeltrieb erforderlich.Dichinomial and mass balancing systems. the dii caused by the cyclical acceleration and deceleration of the whale / framework di.-s cold pilgrim whale / work Compensate for disadvantageous torques, for example in US Pat. No. 29 24 106 and 33 35 593 and DRAS 14 27 951 respectively. The torque compensation is achieved through the provision of additional Balancing weights. which attach to the crankshaft! are. According to the aforementioned publications are the additional compensation measures z. B. arranged in a deep pit, where they either up and slide or perform pendulum movements. In terms of device, this solution is a connection dungssiangc required from the balancing mass to the crank drive.
Die Übertragung dieser vertikalen Anordnung der Ausgleichsmasse in eine horizontale Anordnung derselben, wie sie bei senkrechter Kurbelwelle zwingend ware, Würde, /M einer seitlich weit ausladenden Anordnung führen, die als1 nachteilig anzusehen wäre.The transmission of this vertical arrangement of the balancing mass in a horizontal arrangement of the same as they would be mandatory for vertical crankshaft, / M lead of a laterally widely projecting arrangement dignity that would be detrimental to be considered. 1
Hier nun setzt die Erfindung an, indem sie diese als nachteilig anzusehenden baulichen Gegebenheiten bei Verwendung einer horizontal schwingenden Ausgleichsmasse vermeiden will.This is where the invention comes in by considering these structural conditions which are to be regarded as disadvantageous Avoid using a horizontally oscillating leveling mass.
Aufgabe der Erfindung ist es, ausgehend von dem gattungsbildenden Stand der Technik, eine raumsparende Anordnung der für den Drehmomentabgleich erfoiderlichcn weiteren Ausgleichsmasse im Zusammenhang mit einer senkrecht angeordneten Kurbelwelle Ie zu finden.The object of the invention is, based on the generic prior art, a space-saving Arrangement of the additional balancing weights required for the torque adjustment in context to find with a vertically arranged crankshaft Ie.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß zum Drehmomentausgleich des Kaltpilgerwalzwerkes — wie bei Kaltpilgerwalzwerken grundsätzlich bekannt — eine weitere Ausgleichsmasse vorgesehen ist, die quer zu den Gleitführungen des hin- und herbewegbaren Walzgerüstes horizontal gleitend geführt ist und die zu ihrem Antrieb mit einem kulissenartigen, parallel zu den Gleitführungen des Walzgerüstes in einem Schlitz der Ausgleichsmasse bewegbaren Block verbunden ist, wobei der Block auf der Kurbeiwelienkröpfung drehbar gelagert isl.This object is achieved according to the invention in that for torque compensation of the cold pilger mill - as is generally known in cold pilger mills - an additional leveling compound is provided is guided to slide horizontally transversely to the sliding guides of the reciprocating roll stand is and to their drive with a link-like, parallel to the sliding guides of the Roll stand is connected in a slot of the balancing mass movable block, the block on the crank handle crank is rotatably mounted.
Ein Ausführungsbeispiel der Erfindung soll nachfolgend anhand der Zeichnungen näher erläutert werden. Dabei zeigtAn embodiment of the invention is intended below will be explained in more detail with reference to the drawings. It shows

jo detaillierte Erläuterung des Kaltpilgerwalzwerkes selbst wurde verzichtet, da die Einzelheiten allgemein bekannt sind.jo detailed explanation of the cold pilger mill itself was omitted as the details are well known.
Das Kaltpilgerwalzwerk 10 weist ein Walzgerüst 12 auf. indem sich die Walzen 14 befinden. Das WalzgerüstThe cold pilger mill 10 has a roll stand 12. in which the rollers 14 are located. The roll stand
Vt 12 wird in Richtung der Rohrachse durch parallel angeordnete Gleitführungen 16 geführt. Vt 12 is guided in the direction of the pipe axis by sliding guides 16 arranged in parallel.
Die Bewegung des Walzgerüstes wird durch eine ein/ige Verbindungsstange 18 bewirkt, deren eines Ende am unteren Teil des Walzgerüst. !2 und derenThe movement of the roll stand is controlled by a a / ige connecting rod 18 causes one end of which is at the lower part of the roll stand. ! 2 and their

Wie sich aus den Y i g. 1 und 2 ergibt, isl eine vertikale Antriebswelle 20 für das Kurbclsystcm vorgesehen. Die Kurbel ist mit 22 bezcichncl und horizontal angeordnet und am inneren Ende isl cm als Segment ausgebildetesAs can be seen from the Y i g. 1 and 2, a vertical drive shaft 20 is provided for the crank system. The crank is arranged horizontally and with 22 symbols and is designed as a segment at the inner end is 1 cm
π Gegengewicht 24 befestigt Am unicren Ende der Antriebswelle 20 ist ein Kegelrad 26 angeordnet, das von einem Kegelrad 28. das mit einem elektrischen Motor 10 verbunden ist. über einen Riemen 31 angetrieben wird.π counterweight 24 attached to the unicren end of the Drive shaft 20 is arranged a bevel gear 26, the of a bevel gear 28 which is connected to an electric motor 10. via a belt 31 is driven.
■>(> Die horizontale Anordnung der Kurbel 22 ermöglicht es. daß ein Block 32 auf der Kurbelwcllenkröpfunf; 34 drehbar gelagert werden kann.■> (> The horizontal arrangement of the crank 22 enables it. that a block 32 on the crankshaft headunf; 34 can be rotatably mounted.
Der Block 32 befindet sich in einem Schlitz 36 der Ausgleichsmasse 38.The block 32 is located in a slot 36 of the Leveling compound 38.
Diese ist um 40 phasenverschoben mil der Kurbel angeordnet und die hin- und hergehende Bewegung erfolgt in Richtung der Pfeile 40. bei Drehung der Kurbel 22 in Richtung der Pfeile 4.2 durch ein Paar parallele Führungen 44.This is 40 out of phase with the crank arranged and the reciprocating movement takes place in the direction of arrows 40. when rotating the Crank 22 in the direction of arrows 4.2 through a pair parallel guides 44.
Aus den obigen Ausführungen ergibt sich, daß das Kurbel- und Ausgleichssystem sehr kompakt ist.From the above it follows that the The crank and balancing system is very compact.
